Voila-vuetify will be broken with Voila 0.5.0

[martinRenou]

Description

This is a warning that we are making some deep (and breaking) changes in Voila 0.5.0:

• Voila becomes a Lab-remix Switch to a lab-based app for the Voila frontend voila#846. This means that you won't have access to the kernel API anymore here: https://github.com/voila-dashboards/voila-vuetify/blob/master/share/jupyter/nbconvert/templates/vuetify-base/util.js#L152
• Voila will use JupyterLab mime renderers Make use of JupyterLab mimetype renderers voila#1249 This might break your assumptions concerning outputs rendering (I'm not completely sure though, because it seems you are not inheriting from the Voila templates?)

For reference trying to use the template with voici (which is based on Voila 0.5.0) leads to the following error:

This was noticed in voila-dashboards/voici#60.

Thanks for the heads up!
What is the expected release date of 0.5 do you think?

Hopefully next month for JupyterCon

I just stumbled over this Voila-vuetify template which seems to be compatible with voila 0.5.0:

I think they have removed that package... @jhgoebbert do you know if that's the same as this one https://pypi.org/project/voila-vuetify-template-tuwien/#files ? this doesn't work with voila>5

[jhgoebbert]

Yes, that seems to be the case: https://colab.tuwien.ac.at/pages/viewpage.action?pageId=183404699#Voilà-VuetifyDefaultTemplate

yes, it uses voila-0.4.3 :/

[maartenbreddels]

I'm curious, is there a particular feature you need from voila 0.5?

Maybe Voici support :D

Actually no... we are doing an upgrade in our system and we are avoiding all the unnecessary pins in our libraries, but yes, voila~0.4 can meet our current needs.

@maartenbreddels, @martinRenou , I have created a new Voila template based on voila-vuetify, which you can find here: https://github.com/dfguerrerom/voila-sepal-ui. It works with voila<0.5. After spending some time working with this template, I've gained a good understanding of how the templates function.
I am now planning to make it compatible with voila==0.5, and I could also submit a PR to this repository to update it accordingly.
As you mentioned, the Lab-remix changes how we access the Kernel API. Could you give me a hint about where to look to access this API in the new version? It's important because I want to be able to access the _handleMessage and _update_status functions.
